In order to ensure that you download the most up-to-date version of the data, we suggest you retrieve the files from the Zenodo data repository, where we have archived a stable copy. (Zenodo is a repository, hosted by CERN, where scholars can house citable versions of digital work.)

Our Zenodo data repository is linked to the software-sharing site Github, which means that Github users can fork, modify, and push changes to our data. Once you do that, we can create a new Zenodo release, maintaining a trail of attribution that credits all contributors.
